Abstract
Two optical instrument systems designed for measurement of cavitation nuclei were compared by making a series of simultaneous tests of nuclei in a water tunnel. Over a range of tunnel operating conditions, a holographic camera system measured both microbubbles and particulates while a light-scattering system measured microbubbles only.
Bubble concentrations determined using holography were larger than those from the light-scattering system for bubbles up to 50 micron diameter. The small population of larger bubbles led to large statistical error in the holographic results, preventing clear comparison of the two techniques for bubbles above 50 micron diameter.
